# Description:
#   Every IP datagram has a TTL field, which is decremented by one at every
#   router. When a datagram with a TTL of one (or zero) reaches a router, it is
#   discarded and an ICMP ‘‘time exceeded in transit’’ error message is
#   returned to the sender.
#
#   The traceroute utility takes advantage of this by first sending a UDP
#   datagram to the destination with the TTL set to one, two, ... .
